A recent study shows that the most recent property crash in Dublin was just one in a long line of Irish booms and busts recorded over the last 300 years - and that a true recovery can take centuries.
The Irish Times has published the findings of a major study, which went through more than 20,000 deeds covering 10 key streets across Dublin city.
The comprehensive house price index shows Dublin's property market was completely devastated in the first-half of the 20th century.
It found that a decades-long crash saw real values fall by almost 90% between 1906 and 1947.
It also revealed that property in Dublin cost less in 1944 than in 1744.
The team examined deeds covering several areas of the capital.
They found homes bought and sold by historical figures - such as Arthur Guinness, Charles Stewart Parnell, Daniel O'Connell and Jonathan Swift.
Frank Quinn, of the Blackrock Further Education Institute, was one of the researchers who compiled the house price index.
He says the study indicates a real need for regulation.
